[0003] Chinese patents 95223847.0, 95223844.6, 96204708.2, 97202764.5, etc. disclose devices for reducing the impact noise of inclined platform steel pipes, but some of these devices use chain transmission, and some use mechanical structures such as gear meshing. The entire device is complex and huge, and construction and transformation are difficult. , and some require electric motors to drive, and the maintenance cost is high; for small-diameter steel pipes, or the inclination of the inclined platform is not enough, or the transmission of the steel pipes is not smooth due to chains and gears being stuck
Chinese patent 92218059.8 discloses a device that uses electromagnets to transport steel pipes to the collection frame to eliminate noise, but the device is still very complicated, requiring additional hydraulic mechanisms and power, and the transformation and investment are relatively large, which cannot solve the impact of steel pipes on the inclined platform noise

Embodiment Construction
[0019] see figure 1 , figure 2 , a method for eliminating the impact noise of the inclined platform steel pipe is to install a plurality of permanent magnets 4 above or below the inclined platform 1. In this embodiment, the permanent magnets 4 are mainly installed below the inclined platform 1, and the It is described in detail. If the permanent magnet 4 is installed on the inclined platform 1, it can be realized by a support. The permanent magnet 4 and the yoke 3 form a concave pit, the concave pit sticks to the inclined platform 1, the upper part of the concave pit is a steel pipe 2, and the permanent magnet 4, the yoke 3 and the steel pipe 2 form a magnetic circuit. The steel pipe 2 rolls down at the initial velocity V on the inclined platform 1, and the permanent magnet 4 exerts an attractive force on the steel pipe 2 to gradually brake the movement of the steel pipe 2 until it reaches zero at the end of the inclined platform 1, that is, it is in phase with the previous...

An apparatus for eliminating the impact noise of steel pipes on skid bench is composed of sequentially arranged multiple noise reducing units consisting of permanent magnet, two L-shaped yokes and distance regulator. Said two L-shaped yokes and a permanent magnet constitute a concave pit close to said skid bench and a steel pipe is above said concave pit to form a magnetic loop. Said distance regulator passes through said yoke to fix it under said skid bench. Its method is also disclosed.
Description
(1) Technical field [0001] The invention relates to a technology for reducing noise in the transmission or collection of steel pipes, in particular to a method and device for eliminating the impact noise of steel pipes on inclined platforms. (2) Background technology [0002] At present, in the process of steel pipe finishing, finished products and semi-finished products, the steel pipe needs to be transferred from one place to another through the inclined platform. This transmission method has the advantages of simple structure, no extra power consumption, and saves investment and space. However, the steel pipes collide with each other during the free rolling of the inclined platform, making strong noise, and the pulse peak value can reach 130 decibels, which seriously affects the health of the operator. The existing technology to eliminate the noise generated by mutual impact during the collection of steel pipes is to use the automatic control technology of manipulators. T...
